Kindly share your thoughts/suggestion on below crash.
Seeing some strange crashes and these crashes are not reproducible from my end but users reported so many similar crashes.Crash log says application is crashed in thread 0 and after the __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ call in thread 0 I can see a trace 0 ??? 000000000000000000 0 + 0...what does it mean?
Below is a sample crash log.All other crash logs looks same as below.
